Luminescent chemosensors for chiral molecules have drawn significant attention. In this study, a new iridium complex 1 bearing two urea groups and ethyl naphthalene groups was synthesized as a phosphorescent chemosensor for chiral anion recognition. Addition of t-Boc amino acids induced phosphorescence enhancement with the maximum emission at 560nm. As large as KD/KL value of 5.0 was observed for...
A new 7‐nitrobenz‐2‐oxa‐1,3‐diazole (NBD)‐based fluorescent chiral chemosensor (NBD‐1) was prepared and applied to the recognition of the two enantiomers of the tetrabutylammonium salts of N‐t‐Boc‐α‐amino acids and chiral carboxylic acids including naproxen. In particular, the chiral recognition by the new fluorescent chiral chemosensor for the two enantiomers of N‐t‐Boc‐threonine (tetrabutylammonium...
A new colorimetric chiral sensor material consisting of three different functional sites such as chromophore (2,4‐dinitrophenylazophenol dye), binding site (crown ether), and chiral barrier (3,3′‐diphenyl‐1,1′‐binaphthyl group) was prepared and applied to the recognition of the two enantiomers of primary amino alcohols and amines. Among five primary amino alcohols and two primary amines tested, the...
